I see that file_size calls GetFileAttributesEx to obtain file size - that works in a chance of 99.99%. What is the other 0.01%? It's like this - GetFileAttributes(Ex) does not work with system files, say c:\pagefile.sys. It will only return FALSE and GetLastError returns 32 (The process cannot access the file because it is being used by another process. ) Instead, you have to call FindFirstFile which correctly reports file status in all cases.",Bugs,closed,To Be Determined,filesystem,Boost 1.44.0,Problem,wontfix,,
